Using a single power unit and one operator, the K-Tec 1237ADT Train doubles up efficiency by pulling two 1237 scrapers. On job sites with longer cut-zone and haul road areas, a massive advantage is gained to provide a tandem heaped capacity of 74 Cubic Yards. The 1237ADT Train provides impressive production performance at the end of the day. This configuration has an added advantage since it can split into singles on your job site as conditions change. The K-Tec 1237 ADT Train is designed for self loading with a 40-ton, 400+ horsepower rock truck. The 1237 ADT Train offers more power to the ground with the functionality from an existing rock truck unit. It features fast hydraulics, a smooth ride, and joystick scraper control.
